Davie—I disagree that DNA should be used in the fashion you are suggesting. Like LaVern says, the registry cannot/should not be able to just re-issue papers to some gelding that used to have them when Joe owned him but no longer has them now that Mary owns him. Because what if…
What if this gelding, we’ll call him “Red”, was stolen from Joe’s pasture one night 5 years ago. The thief sold him through the auction and Dixie bought him, and then when Dixie’s kids didn’t like him, she sold Red on to Mary. So now Mary tries to get his papers, based on his DNA, and the registry comes up with Red being Registered Red, belonging to Joe. Why should Mary be able to get papers on Red in her name when Joe never voluntarily signed him over to anyone? Maybe his papers are flagged at the registry, so registry officials get Mary’s DNA and registration request, and they notify Joe that Mary has his horse. Joe loved that horse and wants him back, and contacts police who then go & talk to Mary. In this case DNA is good for Joe, not quite what Mary wanted though!
Or what if Joe sold Red to Dixie on payments…Joe let the horse go to his new home after receiving a down payments, thinking he would get the rest of his money in installments as he & Dixie agreed. But, when Red arrived at Dixie’s place Dixie decided she wasn’t going to pay any more money to Joe—instead she just resold the horse to someone else and told Joe that Red had died and she wasn’t going to pay him any more money. So instead of $1500 for Show Quality Red, Joe has a mere $300 and Red’s registration papers. Now that Red has been sold on a couple of times and Mary has him, why should she be able to send in DNA, find out that her gelding is Show Quality Red who is just 5 points away from his HOF, and have the registry take Red’s papers away from Joe and give them to her??? At most she should be able to use that DNA to find out that yes, Red is registered, that Joe is his registered owner, and contact info for Joe….so that she can call Joe and find out that he will send Red’s papers to her if she pays the balance that is owing on Red.
